Can I Delete "user.dll" Infected W/ Trojan.pandex

Yesterday I removed a WinAntivirus2008 infection from a machine, but today, TrendMicro has identified a file named 'user.dll' as infected with 'Mal_patch_1'. This seems to be a general identifier for worms similar to Trojan.Pandex(Symantec). It is located in the Windows\System32 folder.

Is this a legitimate Windows file, or something made up by a virus/worm?

I renamed it 'user.old', and the computer did not crash, but I did not restart it.

Anytime you come across a suspicious file for which you cannot find any information about, the file has a legitimate name but is not located where it is supposed to be, or you want a second opinion, submit it to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.-- Post back with the results of the file analysis.
